Abstract The results of a year's survey on the parasitic infestation of the gastrointestinal tract of three species of benthic fish, namely Serranus scriba, Mullus surmuletus, and Scorpaena porcus, living in a restricted coastal seaground in the N/W sector of the Gulf of Palermo, are reported and critically discussed. Fish populations were sampled monthly by means of a trammel net, according to the local fishing usage. As many as nine helminth species, five of them trematodes and four nematodes, were collected from the gastrointestinal tract of 625 individuals. Infestation was most intense in M. surmuletus, with a peak in the spring. S. scriba was especially parasitized during the spring an…
Food partitioning between Serranus scriba and Scorpaena porcus (Perciformes) on the infralittoral ground of the South Tyrrhenian Sea.

Food preferences of Scorpaena porcus and Serranus scriba were investigated from the stomach contents of fish caught with trammel nets in the Gulf of Palermo (Tyrrhenian Sea). Decapoda Natantia and Decapoda Brachyura were the main preferred prey in the diet of S. porcus whereas Decapoda Natantia, Decapoda Galatheidae and Pisces were the preferred prey for S. scriba. These results and the values of the index of overlapping alimentary requirements suggested competition for food resources between the two species. A more precise investigation, at species level, of the food remains of the most abundant taxon (Crustacea Decapoda) made it possible to demonstrate that the trophic niche overlap betwe…
